[Bug target/28183] New: [4.0/4.1/4.2 regression] assembler error "FATAL: can't close x.o" on m68k with new binutils

[ forwarded from http://bugs.debian.org/375519 ]

We get the following assembler error when compiling the application cln.  The
error goes away when you drop -fPIC or when you use gcc 3.4.  Additionally, the
error does not show up with older releases of binutils.  While 2.16.91 20060413
produces the error, 2.16.91 20051117 works fine.

I'm not sure if this is a bug in binutils but given that gcc 3.4 works I'm
filing it as a gcc bug.  Andreas, since you're also involved in binutils, I
hope you know where to put the blame. ;-)

What I said about binutils might be wrong.  It seems it's not due to a
difference in the version, but due to one being native and one being cross.  I
just upgraded the binutils-m68k on i386 to the same version as that on m68k
native and strangely enough the same .s file works on i386 with m68k-as but
fails on m68k:

native:

(In reply to comment #2)
That would almost mean as is being miscompiled on m68k.

The removed comment says:

-  /* If will do cse, generate all results into pseudo registers
-     since 1) that allows cse to find more things
-     and 2) otherwise cse could produce an insn the machine
-     cannot support.  An exception is a CONSTRUCTOR into a multi-word
-     MEM: that's much more likely to be most efficient into the MEM.
-     Another is a CALL_EXPR which must return in memory.  */

So it looks like point 2 is true.

This bug can be closed, it's really a bug in binutils triggered by some inline
assembly in cln. Here is a bit more info:
